The scientific nature of the ordinary man is to go out and do the best you can.

We have errors to correct. We have probably had too good an opinion of human nature in forming our confederation.

When you're famous you kind of run into human nature in a raw kind of way. It stirs up envy, fame does.

No matter what part of the world we come from, we are all basically the same human beings. We all seek happiness and try to avoid suffering. We have the same basic human needs and concerns. All of us human beings want freedom and the right to determine our own destiny as individuals and as peoples. That is human nature.

To err is nature, to rectify error is glory.

What can everyone do? Praise and blame. This is human virtue, this is human madness.
